CTET Signature Resizer
CBSE CTET Information Bulletin specifies signature uploads in JPG/JPEG format between 3 KB and 30 KB with image dimensions of 3.5 cm (length) × 1.5 cm (height). CTET is stricter on physical dimensions than many NTA entrance forms — you must hit both the cm size and the KB band. Cropping to 3.5 × 1.5 cm first, then compressing to 3–30 KB, matches how the online registration module validates uploads. Use a recent photograph (10–100 KB, 3.5 × 4.5 cm) separately; CTET matches centre photo with the uploaded image.
